I like the way the borla stingers n magnaflow magnapacks sound on the cobras!

 

off road x pipe whatever you get...i have magna flow and it sounds great.

 

i have an almost stock 01 cobra with slp loud mouth 1's. it sound awesome. get complements all the time. it all depends on what u like though.

 

bassani x-pipe with the bassani cat-back sounds like heaven!

 

i had borla cat back and i loved it... constantly getting compliments on the way it wounded by people at stop lights, gas stations, what have you... just my opinion but when i get my cobra im deffinatley getting borla!! good luck man
